Start with what you see in Amazon.

Use EzSeller to diagnose AMZ.LISTING.SUPPRESSED for the exact seller and marketplace. Read current listing issues first, explain the observed blocker, propose the smallest supported change, require approval before any write, then reread Amazon to verify.

Use EzSeller to diagnose AMZ.INVENTORY.DISCREPANCY. Preserve seller SKU, ASIN/FNSKU and marketplace identity, keep inventory buckets separate, reconcile observed evidence, and do not invent missing units.

Use EzSeller to investigate AMZ.REIMBURSEMENT.REVERSED for the exact marketplace and time window. Reconcile observed reimbursement and reversal events, keep private financial evidence out of public output, and state what remains unproven.

Use EzSeller to diagnose AMZ.MARKETPLACE.MISMATCH. Confirm the requested marketplace and returned marketplace are identical. Do not fall back to US or another marketplace. Stop and report the mismatch if identity is not exact.

Use EzSeller to diagnose AMZ.CATALOG.IDENTITY_CONFLICT. Preserve ASIN, seller SKU, UPC and FNSKU invariants, quarantine conflicting evidence, and never resolve identity by silently overriding one identifier with another.

Use EzSeller to investigate AMZ.FBA.INBOUND_SHORTAGE. Reconcile shipment, received, adjustment and reimbursement evidence for the same identity and marketplace. State unresolved units separately from reimbursed units.
